Be it known that I, Anson elf. BENTLEY, a citizen of the United States, and a resident ofthe city of Niles, in the county of Trumbull and State of Ohiojhave invented an Improvement in {reezing Cans, of which the following is a specification. i The present invention relates to improvements in freezing cans for use in the manufacture of ice and particularly to ,an improved construction of can wherein means are provided for introducing air int-of the can to agitate the water which is, toqbe frozen; this being the commonly accepted practice in what isknown astheraw water can-system of ice making. 1

This application is filed as a division of an earlier application filed bvmeon December 27, 1920, Serial No. 433,163. Thatapj lication showed several embodiments of the invention disclosed therein and the present application will be confined to one of those embodiments vThe claims appended -hercto will be directed to the particular embodimentof the invention shown herein; the invention common to the several forms being claimed in the above mentioned appli-- cation. I

In the raw water can system of ice making it is customary to immerse freezing cans in an appropriate freezing brine. and circulate this freezing solution around the cans. In order that the impurities commonly present in water available for the manufacture of ice may not be frozen into the finished cake, the water is agitated during the freezing operation.

This agitation may be effected bvyan air current and the action is such that the im purities are not frozen into the cakebut are collected in the small amount of water which remains unfrozen in apocket in the ice cake at the termination of the freezing period Inorder to introduce this air current it has been customary to provide some sort of a separable tube orpipeextendinqfrom the top edge of the can downwardly to a point at when the bottom and there open- .ing into the interior of. thecan. or pipe was so arranged" that its 'upperend =located-inside the can it lingured during the freeziiw solution such as This tube forms the side wall Anson J. BENTLEYQ'OF nILEs, OHIO.

' a rnnnznveoaivq this application filed could'be' connected with a source of c0mpressed air and when the can was inuse, air wasforced through the tube out into the water, thus agitating it with the result above; described. As I pointed out in my jammed or torn loose or otherwise injured as thecans are beinghandled. The liability to injury of any exposedpart of the can will be immediately apparent when it is bornein mind that these cans usually contain three hundred or more pounds of water or'ice as the case may be. Ifthe air tube is is very apt to be of the water or to be torn loose when the ice cake is dumped out of the-can.

It is an object of the present invention so to construct a freezing can that a conduit for the introduction of air may be provided without the use of the usual separate tube or pipe, thus iroviding construction and at the same time effecting substantialeconomy in manufacture. L The embodimentxof the invention, which has been made the subject matter of this ap plication is shown in the accompanying drawings whereln,

so far and the bottom and the joining of the several parts are concerned.

The can shown may comprise two pieces of galvanized sheet metalyone of which 1 and the end wall 2,

as the formation of the side walls while the other forms the side wall 3 and the end wall 4r. A third piece of sheet metal may be suitably shaped to form the bottom 5 of the can. The side walls -may be formed, desired, with grooves 6 in order to stiffen them.

For convenience in manufacture the seams of freezing cans of the type here shown are usually formed at diagonally opposite corners although a seam or seams might be located elsewhere. In this respect they can shown in the drawings is of the usual construction. The air conduit presently to be described, is conveniently formed adjacent one of the seams. Obviously a conduit might be provided adjacent another seam, if desired.

To provide the embodiment of the present invention herein described, the vertical edge of a side wall member 3 is abnormallyextended and folded back upon itself. As illustrated, this folding is done in a direction which will ultimately be toward the interior of the can. Thus a conduit 7. extending substantially the entire length of the wall member 3 will be formed.

In order to provide an opening for the escape of air into the'can, the lower end of the folded portion maybe cut away as indicated in Figure 3 thus leaving an opening 8; or if desired, the folded over portion may extend substantially the entire length of the side 3 and a hole 9 may be formed toward the lower end of the conduit as clearly shown in Figure l. If it is desired to provide more than one opening for the escape ofair, other holes may be made in the conduit.

The conduit having been suitably formed in the manner indicated, the can may be assembled in accordance with the usual practice, that is to say, the side walls ma be brought together and riveted where they overlap. The rivets along that seam shown in Figures 3 and f will pass through three thicknesses of metal, thereby holding the folded back extension, the side wall 3 and the end wall 2- securely together. The side seams may be rendered fluid tight by soldering in the usual manner.

The bottom may now be assembled with the side walls, riveted in place and the bottom seamssoldered. The bottom of the can when it is assembled with the sides will con stitute an end wall of the conduit 7; the

opening in the conduit as shown in Figure 3 being at its lowermost end and as shown in Figure 4 slightly spaced from the lower end. The usual reinforcing band maybe placed around the top of the can and suitably riveted in place i Anappropriate fitting designed to cooperate with the 1: articula'r system in which the can to be used may be suitably attached to the upuer opening of the air condu it.

and to another overlapping edge portion.

within the scope of the subjoined claims.

I claim as my invention:

1. As an article of manufacture, an ice mould having a portion of one of the walls bent over upon itself to form an air pipe, 'coinn'ion means for securing said bent over portion and an'adj'acent wall of thetank together, substantially as described.

2. A container for use in the manufacture of ice having a wall member abnormally extended beyond a seam in a wall of said container, a part of said extension being folded back toward said seam'and riveted near its edge to said wall member to forma complete fluid tight conduit extending from the top substa'ntiallyto the bottom of the container whereby air under pressure may be introduced into said container to agitate water that is to be frozen therein.

3. A freezing can for use in the manufacture of ice having an integral air conduit ex tending vertically along a wall of the can and formed by a folded edge ortion of a- '100 wall member, and a means uniting both the folded edge portion to" itself and to another edge portion of a wall member.

at. A freezing can for use in the manufacture of ice having an i'nteriorly located in 105 tegr'al airconduitextend'ing vertically along a wall of the can and formed by a folded edge portion of a wall member, and a means uniting both thefolded edge portion to itself 5. Afre'e'zi'ng can for use in the manufacture of ice having an edge portionof a wall member bent bacl'r upon itself and spaced along the bend. to form airconduit and common fastening means for s'eci'ir'i'ng to-' geth'er the two thicknessesof said folded portion and another edge 'portion, the said conduit having an opening near the bottom ofthecan.

Aconta ine'r for us'ein the manufacture 'o'fice having a wall member formed with an integral eXt-e'nsionbe'yo'nd a seam, a part of said extension being folded inwardly and back upon itself in thedireetidnof the seam, spaced ad'acent the bend and securely fa's 12E "tened atits edge to the main wall member,

uniting both the folded edge portion toitself and to another edge portion of a Wall 10 member.

In testimony name to this s April, 1922 whereof, I have signed my pecification this 24th day of ANSON J. BENTLEY.
